HEEL-ATTACHING DEVICE.

Application filed February 19, 1919, Serial No. 277,932. Renewed November 29, 1922.

To aZZ whom it may concern:

Be it known that I, Josnrrr H. Porn, a citizen of the United States, residing at Hamilton, in the county of Essex and State of Massachusetts, have invented certain Improvements in Heel-Attaching Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to heel attaching devices and, more particularly, to a device for use in attaching wooden or other ogee heels which must be secured by nails or screws driven from the inside of the shoe.

In a considerable number of factory made shoes, and in substantially all repair Work, heels of the type mentioned are attached manually, the heel usually being located by hand upon the shoe sole according to the judgement of the workman and attached by nails or screws driven by hand inside of the heel portion of the shoe. In this method of heel attaching, the heels are often inaccurately located and frequently slip while being attached, with resulting detriment to the appearance of the shoe.

The object of the present invention is to overcome the difliculties above outlined and to provide an appliance for facilitating thev minimum of skill on the part of the operator. To this end an important feature of the invention resides in novel mechanism for supporting and locating a detached heel with its seat face exposed to permit a shoe to be adjusted upon it, and then clamping and holding the shoe and heel securely together while the fastenings are being driven. In a preferred embodiment of the invention the heel is grasped and held in a device or holder in a convenient position to permit the shoe to be placed upon it and a swinging clamping member is arranged to enter the shoe while thus positioned and clamp it firmly to the heel. The clamping member may include means for determining the lo.- cation of the fastenings, and a further feature of the invention consists in so organizing the clamping member or the positioning means that it may be collapsed with its fastening-locating means to permit its easy introduction into the shoe and then expanded to engage the inside of the counter portion of the shoe to insure the proper location ofthe heel seat in accurate register with the heel.

These and other features andadvantages of the invention will be clearly understood from reading the following detailed description of one practical embodiment thereof in connection with the accompanying drawings, in which- Figure 1 is a view in front elevation showing the mechanism with a shoe and heel in position for inserting the heel attaching fasteners;

Fig. 2 is an end elevation of a portion of the device;

Fig. 3 is a perspective view of the clamp ing member and template;

Fig. 4: shows a detail of the heel supporting and locating device; and

Fig. 5 is a fragmentary,-sectional view illustrating the manner of preparing the work and driving a fastener. Y

My improved heel attaching device is especially useful in repair shops and, with that fact in view, it is preferably constructed in a conveniently portable form and arranged to be secured quickly and easily-to any work bench or table. Referring now to Fig. 1, the edge of a bench or table is shown at 8. The heel attaching device is provided with a flat base arranged to rest upon the table 8 and provided with a downwardly extending arm 12, through which is threaded a clamping screw 14, by which the device may be easily and quickly secured to the table. A pair of uprights 16 rising from the rear portion of the base member 10 provide bearings for a longitudinal rod 18, upon which swings a cradle 20,

the base plate 22 of which carries the oper v ating mechanism.

Guide slots 24 are formed in the cradle 20 to receive co-operating portions of an adjustable block 26. A thumb screw 28,- held from longitudinal movement in a stationary bearing 30, is threaded into the block 26, as shown in dotted lines in Fig. 1 and serves to adjust the block lengthwise of the guiding grooves 24.-

A pair of crossed arms 82, 34 is mounted upon the block 26 by a pivot 36. The rearward extensions of the arms 32, 34 are connected by a right and left screw 38 pro- Vided with a thumb nut 40. By virtue of this construction, the arms or jaws 32, 34 may be easily adjusted toward or from each other to fit the particular heel 42 to be attached. Theheel isshown in cross section in Fig. 4 in its relation to the jaws of the supporting device which serves to sustain the heel and position it for the application of the shoe. The cradle is extended to provide a plate 44 for sustaining the forepart of 'theflshoe' and locating it with relation to the heel so that the heelwill' tread properly. To' this extension a swinging 31'11'1'46' is pivo't'ed, the pivot pin being 'provided with ahandle 48 for moving the arm into and out ofoperative position. In Fig. 1 the arm is shown in full lines; in operative position and indicated in dotted lines in inoperative position. .A lug 50 upon the arm co-operates with an abutment- 52 to' limit the swinging movement of the arm. A spring actuated dog 54 is pivoted at 56 t0 the arm 46 and coof the arm 46, serves as a pivot for two counter gages 68, 70, which are mounted to swing freely about the 'axis of the tube. A spindle 72, provided with a handle 74, 1s rotatably'mounted in a bearing 7 6 formed in "the arm 46, being held. from longitudinal movement therein by a collar 7 8 pinned to the spindleabove the bearing and a transverse bar '80 secured tothe 'lower'end of the spindle below the bearing. Pins 82, m-

'serted" in the endsof the bar 80 and extending downwardly therefrom, are engaged by extensions 84, 86 of the counter gages 68, 7 0, j serving to limit the outward-movement of the gages about the pivot tube 62 under the 1nfluence of'the compression spring The pins 82 are spaced apart to permit the counter gages to expand suflicientlyto engage the largest shoe to be operated upon.

When it is desired to introduce the clamping member into a shoe, the handle 74 is turned, causing the counter gages to be brought together to an extentsulficient to permit the clamp to be inserted in the shoe,

'whereupon the handle is released and the spring 88 causes the counter gages to expand until they'engage the inside of the counter portion of theshoe, to locate the shoe prop erly with relation to the heel.

A series of tubes 90 mounted in the counter gages, together withthe tube 62, serve a'sguides to locate the fastenings and as su'pports for thefastening inserting device,

" screwdriver end of the tool is used 'to insert a screw in theh'ole thus prepared, as shown at 104. p V a a The operation of the device will be apparent from the foregoing description but may be outlined and summarized as follows:

Assuming the clainping'arm 46 to be in the position indicated by dotted lines inF-ignl, the jaws 32, 34 are adjusted to the particular heel to be attached and theheel is 'located in them in the position shown in the said figure.

7 The shoe is now placed upon the heel inthe position shown, with its forepart resting upon the supporting plate 44 and the arm 46 is swung into clamping posi- 'tion, the clamping member comprising the counter gages 68, being collapsed to permitthe said member to enter the shoe readily and then released to cause it to fillthe rear portion of the shoe and position the latter transversely with respect to the heel.

Thehe'el holder may be adjusted by means of the screw 28 to position the heel -longitudinally in exact relation to the shoe and the clamping arm forced downto hold :the

shoe firmly uponthe heel, where it willbe automatically locked'by the dog 54. v

The entire cradle, with the work clamped in position, may, if desired, now be swung about the rod 18 to permit the workto be thoroughly examined to ascertain if the" de sired relative location of the heeland'shoe have been secured. If the result is satisfactory, the cradle is swung back'to the position shown in Fig. 1 and the holes are drilled and'countersunk, using the tubes 62 and 90 to guide the tool. The toolis' now reversed and, a screw having been dropped point first into each tube, the screw driver end of the tool is used to drive the screws to securethe heel and shoe together, The tubes likewise serve in this operation to guide the screw driver and make it possible to perform the operation of driving the screws very rapidly and accurately without Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States 1s:
